Even if they made an extra episode explaining everything that they missed just to please fans it still wouldn't matter because RED JOHN IS DEAD. The most boring uneventful death of all time.
That was probably his mother protecting him with the knife. Jane did say on the TV that he was most likely living with his mother or his sister in a bungalow...anyway where was I'am getting off the track of stupidity...

The episode has come and gone, there is no making up for this. I mean on the Hitler video it asked about it being on a DVD. WHAT!
I'M NOT EVEN GOING TO BUY THE BLOODY DVD and FUND HELLER AND HIS ABOMINATION. NEVER. 

This is a three minute youtube video and there is more talent in this video then the whole mentalist put together  http://www.youtube.com/watch?v=kmP4Xzt0rN4&list=FLr7AHSWpLR-Jqez2-Dsqu3Q&index=3
